function getlocations_fields_field_validate in Get Locations 7.2

Same name and namespace in other branches

1. 7 modules/getlocations_fields/getlocations_fields.module \getlocations_fields_field_validate()

Implements hook_field_validate(). Validate this module's field data.

This hook gives us a chance to validate content that's in our field. We're really only interested in the $items parameter, since it holds arrays representing content in the field we've defined.

Parameters

$entity_type: The type of $entity.

$entity: The entity for the operation.

$field: The field structure for the operation.

$instance: The instance structure for $field on $entity's bundle.

$langcode: The language associated with $items.

$items: $entity->{$field['field_name']}[$langcode], or an empty array if unset.

$errors: The array of errors (keyed by field name, language code, and delta) that have already been reported for the entity.
